Frequently Asked Questions

Why do I need radon remediation?

According to the EPA, radon gas is a major health risk for anyone exposed to it. In fact, it's the second leading cause of lung cancer in the United States.

Radon is a natural gas that forms out of the uranium present in the soil and water across the United States. Because it's without odor or color, it's almost impossible to spot for homeowners, leading to extended exposure that can increase your health risks.

What level of radon requires mitigation?

The EPA recommends a mitigation system for radon levels higher than 2.0 pCi/L. Levels higher than 4.0 pCi/L post significant risk and need immediate remediation. Try to test your home's levels in winter when radon is most prevalent.

What questions should I ask a radon removal service before hiring?

Asking the right questions can go a long way in finding a radon mitigation service you can trust:

  1. Are you licensed to install radon remediation systems in my state?
  2. Are you insured, and does that insurance cover everyone working on site?
  3. Can you provide a free estimate before I sign any contract?
  4. Do you offer a warranty or guarantee on your services and systems?
  5. Do you have any references of past homes where you've installed remediation systems?
  6. What steps will you take to ensure the system is working after install?
  7. What is included in your price? Is it just the installation or also the pre and post-evaluation?
  8. Will your system include a warning mechanism that lets you know if radon levels rise?
  9. What type of mitigation system do you think works best for my home?
